Apple opens Siri generative API with developer controls and safety layers

AI · 6 min read

The new Siri generative API offers multimodal prompts, structured action responses, and a serverless option for apps that need local inference. Apple highlights that developers can choose on-device processing for sensitive flows or route to Apple-hosted inference for heavier multimodal tasks.

A major focus of the release is control: Apple provides fine-grained safety rules, rate limits, and a content mapping layer so designers can constrain how suggestions are presented in UIs. It integrates with Apple's Human Interface Kit to ensure generated content follows platform guidelines for contextualness and transparency.

Early partners include productivity and accessibility apps that plan to use the API to offer real-time summaries, contextual compositional UI suggestions, and voice-driven content transforms. Apple also announced an SDK inspector to audit assistant outputs and trace them back to prompts and data sources for compliance teams.
